HKS have developed the BCD Piston + Connecting Rod Set S07A STEP3 φ64 which consists of reinforced pistons and connecting rods to accommodate higher boost and high output of the S07A engine.
Features
- Piston Kit:
- By using A2618 material, which has high high-temperature strength, it is possible to make the wall thinner, resulting in a lighter weight.
- By manufacturing it by cutting out, HKS were able to eliminate excess material and achieve a lightweight design.
- By adopting a bridge structure, structural rigidity has been improved while also achieving weight reduction.
- The crown surface has the same shape as the original.
- A two-layer coating is used to improve anti-seizure properties and reduce friction.
- Connecting Rod Kit:
- The connecting rod is machined from chrome steel and has an I-beam profile, which is 74% stronger than the stock one.
- To improve fatigue strength, the surface has been treated with WPC.
Notes
- Since it is heavier than the original part, there will be a slight increase in up and down vibration.

HKS was founded in October 1973 by Hiroyuki Hasegawa, a former Yamaha engineer, and Goichi Kitagawa, with start-up capital from Sigma Automotive; the name comes from Hasegawa, Kitagawa and Sigma. It began in a small shed at the foot of Mount Fuji, in Fujinomiya, Shizuoka, and is still based there.
In 1974 HKS built one of the first bolt-on turbo kits, for the Nissan L20 engine in the Skyline, raising output from 115 to 160 PS. Turbocharging made its name; today it also makes exhausts, springs, shocks and coilover suspension, and it marked its 50th anniversary in 2023.
